July 19, 2018

(CNN) – Women who have given birth five or more times may be 70% more likely to develop Alzheimer’s later in life than those who have fewer births, according to a new study of more than 3,500 women in South Korea and Greece. Even women without dementia who had given birth five or more times scored lower on a commonly used cognitive test than those with fewer children. The study looked only at women older than 60; the average age of the women tested in both countries was 71.
